Outdoor activities: take water

Bring water. No matter what you’re going to take you on the way to go through a stream, lake, river or stream, these may be dry, contaminated, or need the water (either for drinking or for cleaning injury) when we are away from them. So you always have to store and carry water for cases like these.
In the particular case of the ascent, trips or routes involving the absence of safe drinking water during the journey, this recommendation is an inescapable requirement.
